Weathering
The process where rocks from Earth's crust are slowly being broken into smaller pieces is called...
Weathering
What is the difference between weathering and erosion?
Weathering breaks rocks into smaller pieces; erosion moves those pieces away.
Lava which cools and hardens, form this kind of rock.
What is igneous rock?
A break or crack in rocks where Earth's crust can move is called...
A fault
Name AND describe the layers of the Earth.
crust- the outer most layer which is formed of rock mantle - the middle layer of the Earth made of hot, slow flowing rock core- the innermost layer of the Earth, the hottest, but packed so tightly that it is solid
What are physical causes of weathering?
tree roots, water freezing/thawing, temperature changes which cause soil to crack
What carries soil away from hilly farm fields?
rain
True or False... A volcano is an opening in Earth’s crust.
True
The vibrations of an earthquake move as?
What are waves through the Earth?
What pulls all objects from higher places to lower places?
Gravity
Explain how plants can weather a rock.
A plant's roots can grow inside a rock, and as they grow, it can break the rock apart.
Name 3 of the 4 ways weathered materials are moved.
Water, glaciers, gravity, and wind
What are the sudden shifts between parts of Earth's crust cause the ground to vibrate in all directions called?
List 3 different landforms.
Sample Answers: Plains, plateaus, mountains, peninsulas, valleys, canyons
How can ice cause physical weathering?
If water gets into the crack of a rock and then freezes, it will expand when it turns into ice. The expanding ice can cause the rock to break into smaller pieces.
Name 1 similarity and 1 difference between landslides and avalanches.
Both landslides and avalanches are rapid downhill movements due to gravity. Landslides are the movement of rock and soil, while avalanches are the movement of snow and ice.
When igneous rock from a volcanic eruption cools, what does it form?
What is new crust?
True or False: Earthquakes can change the shape of continents.
True
How are lakes formed?
water slows enough to fill an area
Name the 2 types of weathering and how they are different.
Physical and chemical weathering. Physical weathering changes the size and physical appearance of rocks. Chemical weathering causes rocks to change into different materials.
In dry areas like deserts, what causes most of the erosion?
What is wind?
What force can rapidly change the Earth’s landscape? a) wind erosion b) volcanic eruptions c) weathering d_thunderstorms
What is volcanic eruptions?
Large section of the Earth's crust which move suddenly in an earthquake are called this?
What are plates?
